Parker PPB8UC6-MG Push-to-connect Union Fitting 1/2x3/8

Product Description

The PARKER PPB8UC6-MG is a push-to-connect union tube fitting designed to join two tube runs without tools. It accepts 1/2 inch and 3/8 inch outside diameter tubing, making it a reducing union for connecting two different tube sizes in a single inline connection. The fitting is molded from polypropylene and rated to 150 psi. Plumbers, HVAC technicians, and fluid-handling service techs install this fitting in low-pressure pneumatic and fluid lines where a fast, tool-free connection is required. Its compact body measures 1.9 inches in length and 1.9 inches in height with a 0.93 inch width.

This fitting is suited for residential and light commercial applications involving tube-to-tube connections in water, air, or compatible fluid distribution systems. The push-to-connect design allows quick installation and removal during service calls, reducing labor time in tight spaces. It is appropriate for inline use where a reducing union is needed between 1/2 inch OD and 3/8 inch OD tubing runs.

Key Features

• Push-to-connect design requires no tools for installation or removal
• Reducing union connects 1/2 inch OD tubing to 3/8 inch OD tubing
• Polypropylene construction offers chemical resistance for compatible fluid and air service

• Compact form factor fits in confined spaces and tight plumbing chases

Compatibility

Designed for use with 1/2 inch and 3/8 inch outside diameter tubing in push-to-connect tube-to-tube applications. Verify tubing material and system fluid compatibility with polypropylene before installation.

Installation Notes

Shut off system pressure and depressurize the line completely before disconnecting or installing any push-to-connect fitting. Cut tubing square and deburr the end to ensure a proper seal and full insertion into the fitting. This fitting is typically installed by licensed plumbers or HVAC technicians following applicable IPC or IFGC guidelines for the system type. Do not exceed the rated 150 psi operating pressure.
